> * On rzg2l_du_crtc_set_display_timing() replaced the setting of parent
> clk rate with dclk rate.
> * Added rzg2l_du_write() wrapper function.
> * Updated the comment atomic_begin->atomic_flush.
> * Dropped .atomic_check and .atomic_begin callback
> * Renamed __rzg2l_du_crtc_plane_atomic_check->__rzg2l_du_vsp_plane_atomic
> _check and moved it to rzg2l_du_vsp.c
> * Added struct clk in rzg2l_du_crtc.h
> * Dropped the variables mmio_offset,index,vblank_lock,vblank_wait,
